The nine-member South Korean troupe is returning in February with a new “special album” called TWICEcoaster : LANE 2, according to a teaser announcement on the group’s Twitter yesterday (Feb. 5). Pre-orders for the album begin on Monday, February 13.

A few days earlier, the group also teased something called “KNOCK KNOCK,” due to be released on February 20, which fans now assume is the release date for TWICEcoaster : LANE 2.

Following the girl group’s debut in 2015 with The Story Begins, Twice have quickly become one of K-pop’s hottest new groups, hitting Top 10 with their “Like Ooh-Ahh,” and notching the No. 1 spot with both “Cheer Up” and the insanely infectious “TT.” Their last mini-album, Twicecoaster: Lane 1, was released in October of 2016.
